Thanks Ondrej!

It will be greater if I can debug (and set breakpoint) in Visual Studio
release mode project and see how related assembly code is for a line of
source code -- like we did in debug mode.

My code is very simple, but I failed to achieve the goal I mentioned in the
above paragraph. Could you try and see whether you can set breakpoint in
release mode and find the related source code/assembly code matching window
please?

To use DebugBreak() you need to include <windows.h>.
After removing the DebugBreak(), the code compiles in release mode, and I can
set breakpoints without any problem. The debugger stops at the break point
(which might not be where you put it due to code removed by the optimizer), but
you can look at the assembler code with Ctrl-F11.

What exatly is your problem? Does your F9 key not work? Does the debugger not
stop at the break points you set?

[Code]
#include <iostream>

using namespace std;

int A[4 * 7];

void foo()
{
    int h = 4;
    int w = 7;

    for (int i = 0; i < h; i++)
    {
        DebugBreak();

        for (int j = 0; j < w; j++)
        {
            A [i*w + j] = -(i * i + j * j);
        }
    }
}

int main()
{
    foo();

    cout << A [0] << endl;

    return 0;
}
